Qhov sib txawv tseem ceeb ntawm cov ntsev soluble thiab insoluble yog cov ntsev soluble tuaj yeem yaj hauv dej ntawm chav tsev kub, hos cov ntsev insoluble tsis tuaj yeem yaj hauv dej hauv chav sov.
Ib ntsev yog ib qho sib xyaw ua ke los ntawm cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus. Yog li ntawd, ib qho ntsev tseem ceeb muaj anion (los ntawm cov kua qaub) thiab cation (los ntawm lub hauv paus). Peb tuaj yeem faib cov ntsev sib xyaw ua ob hom nyob ntawm lawv cov dej solubility ntawm chav tsev kub. Lawv yog soluble thiab insoluble ntsev. Lub solubility ntawm ntsev nyob ntawm seb hom kev sib cuam tshuam lawv tuaj yeem muaj nrog dej molecules.
Cov ntsev ntsev yog dab tsi?
Soluble s alts yog cov ntsev ntsev uas yog soluble hauv dej ntawm chav tsev kub. Cov ntsev tebchaw no yaj hauv dej vim tias lawv tuaj yeem tsim cov khoom sib txuas nrog cov dej molecules. Cov dej molecules yog polar. Yog li ntawd, dej yog cov kuab tshuaj polar, thiab polar ntsev tuaj yeem yaj hauv dej.
Daim duab 01: Sodium Chloride yog Soluble S alt
Vim cov ntsev yog cov ionic compounds, lawv yaj hauv dej vim cov dej molecules nyiam nyiam cov ions hauv cov khoom sib xyaw, uas ua rau lawv sib cais ntawm ib leeg, ua rau cov ntsev yaj. Ntawm no, qhov kev sib cais ntawm cov ntsev tsim cov hom ionic hauv dej, uas ua rau cov kua dej tshiab tsim ua kom muaj zog heev. Cov hom ionic yaj hauv dej tuaj yeem ua hluav taws xob los ntawm nws. Ib qho piv txwv ntawm cov ntsev soluble yog cov ntsev ntsev los yog sodium chloride. Cov tshuaj aqueous ntawm lub rooj ntsev muaj sodium ions thiab chloride ions.
Cov ntsev Insoluble yog dab tsi?
Insoluble s alts yog cov ntsev ntsev uas tsis muaj dej nyob hauv chav sov. Cov no yog insoluble hauv dej vim dej molecules tsis tuaj yeem nyiam cov ions hauv cov ntsev ntsev. Yog li ntawd, tsis muaj kev sib cuam tshuam ntawm cov dej molecules thiab cov ntsev insoluble.
Daim duab 02: Silver Chloride Precipitate hauv dej
Tsis tas li ntawd, cov ntsev insoluble yog cov tsis muaj polar compounds. Tsis zoo li soluble ntsev, kev sib tov ntawm cov ntsev insoluble nrog dej tsis ua rau cov tshuaj conductive vim hais tias cov ntsev tsis cais mus rau hauv ions. Ib qho piv txwv zoo ntawm cov ntsev insoluble yog nyiaj chloride (AgCl).
Qhov txawv ntawm Soluble thiab Insoluble S alts yog dab tsi?
Peb tuaj yeem faib cov ntsev sib xyaw ua ob hom nyob ntawm lawv cov dej solubility. Lawv yog soluble thiab insoluble ntsev. Qhov sib txawv tseem ceeb ntawm soluble thiab insoluble ntsev yog tias cov ntsev soluble tuaj yeem yaj hauv dej ntawm chav tsev kub, thaum cov ntsev insoluble tsis tuaj yeem yaj hauv dej ntawm chav tsev kub. Ntxiv mus, soluble ntsev yog polar; Yog li ntawd, lawv tuaj yeem yaj hauv dej, uas yog lub ntsiab lus polar. Nyob rau hauv sib piv, insoluble ntsev yog nonpolar. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm soluble thiab insoluble ntsev.
Ntxiv rau cov saum toj no, cov dej molecules tuaj yeem tsim cov khoom sib txuas nrog cov ions ntawm cov ntsev soluble, tab sis tsis muaj kev sib cuam tshuam ntawm cov ntsev thiab dej tsis sib haum. Tsis tas li ntawd, kev sib cais ntawm cov ntsev ntsev hauv dej ua rau cov kua dej muaj kuab heev vim tias cov ions yaj hauv dej tuaj yeem ua hluav taws xob los ntawm nws. Tsis zoo li cov ntsev soluble, sib tov cov ntsev insoluble nrog dej tsis ua rau dej conductive. Sodium chloride yog ib qho piv txwv ntawm soluble ntsev, whereas silver chloride yog ib qho piv txwv rau insoluble ntsev.
Summary – Soluble vs Insoluble S alts
Peb tuaj yeem faib cov ntsev sib xyaw ua ob hom nyob ntawm lawv cov dej solubility. Lawv yog soluble thiab insoluble ntsev. Qhov sib txawv tseem ceeb ntawm cov ntsev soluble thiab insoluble yog cov ntsev soluble tuaj yeem yaj hauv dej ntawm chav tsev kub, hos cov ntsev insoluble tsis tuaj yeem yaj hauv dej ntawm chav tsev kub. Ntxiv mus, soluble ntsev yog polar; Yog li ntawd, lawv tuaj yeem yaj hauv dej, uas yog lub ntsiab lus polar. Nyob rau hauv sib piv, insoluble ntsev yog nonpolar.
